Cockroach Bully is a character in the Japanese television series Tekkai Kobo, a B-series robot number eight, the older brother of Detective Spider and Scorpion Lai Lai, and a poor street punk who wants to rule over the human race with the Peace Star.

Cockroach Bully traveled to the African continent with Highlander Temple*** to find out the mystery of the Peace Star. He often fights with Detective Spider and Scorpion Lai Lai for the Peace Star with Kabuta. But most of them failed. When they succeeded, they were mostly given "fake peace stars". In the grand finale, he turns over a new leaf and obeys Dr. Takaharaji, who created him, to discover the mysteries of the Peace Star.

Cockroach Bully Character History:

Originally created with a grudge against Shark Pepper. After the learning process, wanted to improve the robot's status, and to that end wanted to take over the Peace Star to become president, battling Kabuta several times.

Cockroach Bully looks evil on the outside, but actually has a gentle, romantic heart. He once fell in love with the single mother of a young boy, but found out she had remarried when he was about to propose.

In episode 50, "Chocolate Represents a Man's Pure Love", he receives a lot of chocolates on Valentine's Day, but most of them are "giri" (ordinary sentimental chocolates, used only for friends of the opposite sex and not for romantic partners), including the bento store clerk he adores! --Ms. Yumiko Kokubunji.

He was so upset by this that he desperately grabbed the Peace Star to try to make her fall in love with him. In fact, Yumiko loves him in her heart, but she accidentally sent the wrong chocolate to the cockroach bully. She really wanted to give the cockroach bully the "True Fate" (True Fate Chocolate, which is used to give to one's significant other and the one one one adores), and forgot to give it to him on Valentine's Day.

Writing a love letter contest he thought of Ms. Yumeko made for him salmon bento and her beautiful smiling face, so he used the most sincere thoughts in the land dug out a very large confession "you are my salmon bento", touched everyone and won the victory.

After realizing that the Star of Peace was a fake, he was disappointed when Kabuta happened to see that the wrong "ギリ" chocolates from Ms. Yumeko weren't for him, and advised him not to be upset - the cockroach bully turned around and accepted the chocolates from Ms. Yumeko. The cockroach bully turns around and accepts the chocolates from Ms. Yumiko. (The Cockroach Bully thus becomes friends with Kabuto and is no longer an enemy.)

Episode 51: The Cockroach Bully is converted and obeys Dr. Takaharaji, who created him, and goes to war with Shark Pepper over it. Episode 52 joins the others in the fight against the Peace Star Guardians.
